To all whom it may concern:

Be i .lmown' that we, JOHN W001). and

, WILLIAM ARMSTRONG, subjects of the King in the county of-.'G1'eat Britain and Ireland, residing at Garden Engineering Works Ramsbottom, of Lancaster,. ngland, have invented new and useful Improvements in Apparatus for Printing Magazines, and- Such like Work, of which the following is a specification. v Y

-.lhisinvention relates to a machine or apparatus for photogravure or intaglio printing whereby reproductions by photogravure processes can be obtained and printed on one but usually on both sides of a passing web. Such processes are at present in. use andineed not be dealt with here,'it being suficient to 'say' that twoseparate head or printing the two backing owls and the two" printing -cylinders or rollers so that the same are adjacent to each other and located 'at one end of the apparatus. In. efie'ct we use according to our system a duplex printing arrangement and have all the parts combined and grouped atone head and whereby thepaper can pass to and ire in more or less vertical or inclined paths instead of having horizontal or. approximately horizontal travel I i i In the machine or plant we prefer to employ a fluid cooled roller'or rollersxtor cooling the passing web or paper, which is an important feature inour proposed apparatus for duplex photogravureprintmg.

We also arrange to so carry the. printing cylinders or rollers that same can he simul passes to be till - the invention by a full description of one taneously adjusted or moved with respect to the backing bowls over which the paper rinted, or, alternatively, we arrange to ad ust the backing bowls to the printing cylinders or rollers. We will now proceed to clearly indicate form of rinting machine which willcarry out our 0 ject, and which combines the features of novelty above indicated, and, in this'description, the attached drawings will Specification of Letters Patent.

In the said drawings: Figure 1 shows a general side elevation of-a single color duplexor perfecter photogr'avure printing machine of the typeand possessing'the features indicated in the pre- Fig. 2 is a detail section of a water cooled.

roller which we prefer to employ.

Fig. 3 is an end view of Fig. 2. Referring in particular to the construction' illustrated generally in the attached drawing, we take the paper A to be printed from a batch 'or reel such as A" at one end of the apparatus and lead same upward to drawing rollers a a or such like, then" down if necessary and over a saddle such as is marked 6. From the saddle, the paper A 1 preferably passes downward to a rollers" and from thenceit may pass in a horizontal direction and over rollers 03 we toward the printing mechanism to which it preferably passes upward from below. -The actual printing combination comprises end frames I f f in which are carried two sets of backing bowls and printing cylinders or rollers, that is, a backmg bowl and printing roller for each side of the-paper. The backing bowl in thefirst 'set'is marked 9' and the printing cylinderflor roller 7, while the back-- ing bowl of the second set is marked g .agd 3 the printing cylinder or roller it.

shown, the .two sets lie adjacent and are interconnected for driving and other purposes and this is preferably done by spur wheels on'shafts. or'st'uds carried by the end frames. The driving arrangement ilhistrated is a very simpleone, and, consists of a main driving shaft '5 having a spur wheel ?I, said shaft having fast and loose pulleys if-or, being driven by gear. The spur wheel 71' gears with a, crown or spur wheel 5 1 on the first impression bowl shaft and this wheel i meshes with a spur wheel e onthe first printin cylinder or roller h as is clearly shown.

ntheleft of the spur 1 wheel a .is an intermediate, spur wheel j on the stud. orother'sh aft j,and this intermediate spurwheel" j gears into the crown or sur wheel 1' on the second backing bowl which crown or spur wheel 9' gears into and. drives the spur wheel j on the second printing cylinder or roller k;

The ascending paper A traveling over the roll 2 passes between the :first backing bowl g and-printing. roller k and is printed as to one lace, and then goes upward and water cooled roller Z which contains water i or has cooling liquid circulated therethrough. Such roller is very clearly illustrated in detail by Figs. 2 and 3 of the drawings. The hollow shafts Z Z are suported by hollow brackets Z Z said shafts eing properly packed by packing and glands as shown.

Water or cooling liquid enters at Z passes through the hollow roller Z and leaves at the outlet 1*.

This roller Z effects cooling of the paper, and, from that, the paper passes between the second backing bowl 9 and the second printing cylinder or roller. h. The drying cylinder and water cooled roller or rollers are most conveniently situated immediately above the duplex printing mechanism, as the drawing shows, and can be easily supported .by girders or framework. In connection with the second backing or impression bowl 9' we use a traveling backing blanket m which passes over suitable guide rollers m and is kept suficiently taut by the tension device m.

After leaving the second printing ele-.

ments, the paper is led upward over guide rollers and passes across suitable drying sheets, chests, or the like to thecutting machine.

In order to have proper control over the printing mechanism we find it necessary ing short extension levers o to which links to providemeans to adjust or move the printing cylinders or rollers and attendant parts and with this object in view we may lowerhorizontal lever n fulcrumed ,at n

To similarly influencethe second printin cylinder or roller h, we also utilize additlonal inclined or other-levers g fulcrumed at and such levers carrynuts for. screwe adjusting spindlespg which act on the bearing blocks.

of the secondprinting cylinder or roller h. The levers g are acted on and connected by jointed to the short =extensions 1 ing cy menses 0 influenced by the lower horizontal lever n. Adjustable weights 8 on this lower horizontal lever n keep the printing cylinders or rollers up to their work. To etfect' simultaneous lowering or adjustment of the printing cylinders or rollers we provide a hand lever 22 pivoted at t and having a cam t which cam acts on the lower horizontal lever 11. and raises the weighted end. It willbe quite understood from the preceding description of the lever and link mechanism that the requisite levers and links are duplicated at the other end of the machine sup I ported by the frame and connected across as necessary.

Instead of the above described arrangement, or in addition thereto, we ma arrange to be able to raise or lower the acking bows g, 9. We show an obvious way of doing this according to which the backing bowls are carried in adjustable bearings g g* to which screwed spindles u u are fitted and which work in thelframe. screwed spindles are actuated by beveljgear '0, o, as indicated, and the two setsof gear may be interconnected so that ad ustment of both bowlscould take place simultaneously.

' By directing the sagging does not ta e place, and correct register is insured.

The whole construction makes for extreme compactness and efliciency and the entire printing mechanism is localized at one point. l

In case 1t is found that the ink can be Said.

a stationary saddle, a drying cylinder arran ed .above'the impression wls, a water coo mg cylinder arranged between the dryimpression bowls.

batch nder andthe impression bowls, and a positive driving connection between the supporting means, draw rollers, a saddle,

and guide rolls 1n combination with end frames supp'iqlrting two impression- 'bow1s,

Pr =y ders below the bowls, sup- 1'" menses ports therefor, adjusting devices for the cylinders comprising lever mechanism, a drying roller and additional guide rollers and a water cooled roller through which water is caused to fiow, all in combination, and for the purpose set forth.

3. A duplex or erfecter photogravure or like printing mac ine comprising a single head, single end frames, two impression bowls supported by said end frames one above the other in relatively close relation, a positive drive connection between the bowls, two printing cylinders arranged one above the other for col'iperation with the under surfaces of the impression bowls, means to fll'lOVr "y support the cylinders, means for gei the paper and means for simultaneousl adjusting hoth printing cylinders with relation to the impression bowls comprising a, horizontal lever, shaft on which the lever is fulcrumed, other levers tuate the first mentioned lever to raise and lower the lowermost printing cylinder, and linkand lever connections between the first mentioned lever and the supporting means of the uppermost printing cylinder, whereby upon actuation of the operating lever both of the printing cylinders may be raised and lowered toward and away from the under surfaces of the impression bowls:
